摘要: 提出了一种变结构控制平滑方法,推导出变结构控制系统的稳态误差指标与饱和特 性宽度之间定量的数学关系,通过系统的稳态误差指标可以设计出宽度变化的饱和特性.仿 真结果验证了该方法的有效性.Abstract: This paper presents a method of softening variable structure control. The mathematical relationship between the steady-state errors and the width of saturating property is presented. Through the specification of the steady-state errors, the saturating property with varying width can be designed. The simulation results prove the validity of the method.
